Great shots, Rube. Looking at the photo of the folks crossing the bridge, your pictures would have to be from about 1980 or maybe '81. The management had a crawling net placed on the bridge around 81 or 82 to prevent adults from going inside...I don't know this for sure, but my personal belief is that the treehouse was becoming unstable and I guess they figured by keeping big adults out of it, it might last a few more seasons. I do know about this time period they reinforced the legs on the treehouse, because I witnessed the maintenance and construction crews doing the work. The 1980-81 period is when Tom Sawyer's Landing was new and the treehouse had been rethemed to Huck Finn's Hideaway to fit in with the adjacent "landing." Thanks for sharing, and I hope you can get your pops permission to wade through all the family photos soon, so we can see more of them here.
